"The public have been very helpful to this point but we are really looking for that final piece in the puzzle and we think this image will give us a good identification of this male," Inspector Binyon said.

"We think it's a good quality image and we're very confident that someone knows this person, they will be able to identify him readily from the image, from the detail in the image, and we would ask anyone who knows that person to contact CrimeStoppers."

Police say they are also searching for the victim's handbag.

Inspector Binyon says the victim has been released from hospital after having surgery for significant head and facial injuries.

"She has had plastic surgery to correct a deep laceration to her face," he said.

He says the victim has been receiving counselling, and has been reunited with her family who have flown from interstate.
